摘要
the characterization of courtship and mating behaviors in callisphyris apicicornis (coleoptera: cerambycidae) is important in the eventual development of strategies of control/management, based on behavior modification mediated by the sex pheromone of this species. the behavioral sequences of c. apicicornis were filmed in the field (la pintana, regi車n metropolitana, chile, between september and december 2009 and 2010). also temperature, wind speed, and time were registered. the videos helped identify and describe the steps included in the sequences and their respective frequencies. results showed that in this species the sequence is highly stereotyped, of first order and does not occur randomly, attributes that suggest a pre-programming of the individuals that would allow contact with toxic baits or specific monitoring systems. in males, the sequence consists of: approach, mounting, approximation of genitalia, copulation, undocking, guarding, and departure. the female generally remains stationary during this stage, except when it rejects the male, escaping from it or hitting it with its hind legs. these behaviors were significantly influenced by environmental temperature, whereas wind speed and time of day did not significantly affect behavior. it was also noted that the female of c. apicicornis was able to attract males of another species (hephaestion violaceipennis) belonging to the same subfamily (lepturinae), which were rejected in the same way the conspecifics were.
